WordPress Expert Needed to Improve Booking Plugin

Hey! I need a WordPress developer to fix and improve my booking plugin. Right now, it's too basic, and it's driving me crazy. Guests can’t modify their bookings, which means every time someone wants to change dates, I have to cancel and rebook manually. I need a way for guests to adjust their own reservations without my constant involvement.

Also, I want to add a partial payment option—right now, guests have to pay everything upfront, which scares some people away. Plus, I’d love an automated alert system that notifies people when dates open up. If you know WordPress, PHP, and plugins, hit me up!
